Abstract
The joint acquisition of color and near-infrared (NIR) images is a fast growing field due to various applications that make use of the additional spectral information. The silicone sensors of most cameras are sensitive to NIR light which is blocked using an additional filter. By simply removing this filter, NIR can be acquired on a broad range of imaging devices and leveraged for multiple applications. Our current objective is to solve the limitations present in depth estimation from defocus blur by relying on NIR information. In this proposal, we survey three works from the field relating to the carried research. The first provides an in-depth study of chromatic aberration and NIR imaging, its correlation with color and its deblurring. The second paper works on the estimation of defocus maps from single images. Lastly, we cover a paper that addresses one of the limitations of depth-from-defocus, namely figuring out which side of the focal plane an object is on.
